The 2403 is the 28 inch Blackstone with three independently controlled zones, which is the feature that matters most at this size. With three zones you can sear at one end, cook at medium in the centre and hold food warm at the other end, rather than treating the plate as one big hotplate.
The listing calls this the XL, which suggests a plate with more room than the standard 28 inch models, though you should compare any stated area rather than trusting the name alone. The Omnivore plate carries the wind guards and faster preheat typical of the brand, and the hood keeps the surface clean between uses.
Against the two burner 2367 that shares the 28 inch label, the 2403 costs more but gives you the extra zone and the extra cooking flexibility. If you cook full meals instead of just breakfast, that third zone is worth paying for. The usual routine of scraping hot, oiling and covering applies, and the hood adds some protection but is no replacement for a soft cover in wet seasons. Setup is the part owners underestimate, because a three burner cart with a hood and shelves takes a patient hour with the instructions and a helper for the heavier lifts. Once it is together, keep an eye on the knob and igniter connections after the first few uses, since new hardware settles in. It is also the model to choose if you plan to keep the griddle for many years, since the zone control is the feature people grow into rather than out of.
